# What does "Device limit reached" mean?

Free accounts sync on up to 2 devices, and this dialog appears when a third tries to register. Remove a device you no longer use directly in the dialog, or on an existing device under Settings > Account ([how removal works](https://privacynotes.app/help/remove-device/)). The slot frees immediately, and the removed device stays visible under "Recently removed" for 72 hours. Pro lifts the cap entirely.

Several browsers on one computer count as a single device: they are grouped using privacy-preserving hashes of coarse machine signals, computed on your device with a per-account secret. A major browser update, or a hardened browser like Brave or Tor that randomizes those signals, can land the same machine in a new slot. Remove the stale entry and carry on. You are never locked out.
